A miniature microphone component comprises a miniature microphone having a terminal area; a rubber casting for protection against vibration covering the circumference of the miniature microphone; and a rubber connector with anisotropic conductivity comprising an electrically conductive layer and an electrically isolating layer, which is clamped and retained so as to have areal contact with the terminal area of the miniature microphone. The miniature microphone, the rubber casting for protection against vibration covering the miniature microphone and the conductive rubber connector are integrated into one component. The rubber connector with anisotropic conductivity is shaped so that none of its electrically conductive layers has contact with more than one terminal of the miniature microphone at a time. The miniature microphone component can be installed simply by pressing it against a terminal portion on a circuit board in a small-size mobile communication device such as a mobile phone. The steps of soldering and wiring a lead wire can be omitted and the installation space can be minimized.
